Extract

Antipsychotic agents have been the mainstay in the management of schizophrenia for a number of years. Their therapeutic efficacy is primarily attributed to dopamine receptor antagonism (Creese et al, 1976), leading to a reduction in the positive symptoms of schizophrenia such as paranoia and hallucinations. Unfortunately, they have little effect on the negative symptoms (such as flattened affect, poverty of speech, anhedonia and social withdrawal) or cognitive deficits. The blockade of central dopamine receptors by classical antipsychotic agents also leads to the development of both acute and chronic motor disturbances (extrapyramidal side-effects) (EPS) (Meltzer, 1992).
